Chain Smoking Asians: A bunch of Asians who like to chain smoke at various places non-stop. However, other people who participate in these activities with or without Asians can still be called a CSA. These activities usually happen in social settings.
Guy 1 (Asian): Hey I'm getting tired of dancing, wanna go CSA outside for a bit?
Girl 1 (Not-Asian): Yeah, let's go CSA and get some air.
Girl 2 (Asia): Hey! I'll come CSA with you guys too.
